Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a ruler for measuring the height difference at the four corners of a bridge bearing. Background Technology

[0002] Bridge bearings are the core force-transmitting components that connect the superstructure (such as beams) and the substructure (such as piers and abutments). If the height difference error at the four corners of the bearing is large, it will break the original force balance and deformation coordination design of the bearing, which may cause a chain of damage from the bearing itself to the upper and lower structures of the bridge, and in severe cases, it may even threaten the overall safety of the bridge.

[0003] During and after the installation of bridge bearings, the height difference error of the four corners of the bearings must be controlled within 2mm. Currently, the common method for measuring the height difference of the four corners of the bearings is to place a laser level at one corner of the bearing pad stone and read the scale on the steel ruler or tape measure where the laser shines. However, this method cannot guarantee that the steel ruler or tape measure is always perpendicular to the steel plate, which can easily cause human error. It is not conducive to the control and measurement of the height difference of the four corners of the bearings. Utility Model Content

[0010] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments: like Figure 1 As shown, a height difference measuring ruler for the four corners of a bridge bearing is used to detect the flatness of the bearing. The height difference measuring ruler is right-angled. The main body of the height difference measuring ruler consists of a measuring scale 1 and a telescopic measuring rod 2. The measuring scale 1 is fixedly connected to the bottom end of the telescopic measuring rod 2 at a 90-degree angle, and the whole structure is "L". During measurement, the measuring scale 1 is placed at the three corners of the bearing, and the scale of the measuring scale 1 is read after leveling with a tubular horizontal bubble 3 and a circular horizontal bubble 4. Finally, the relative height difference value of the four corners of the bearing is obtained by calculation.

[0011] The measuring ruler has a telescopic structure and a dual bubble level calibration function, which facilitates precise positioning in narrow spaces and ensures the accuracy of measurement data.
